In a recent paper, Wang et al. (J. Anal. At. Spectrom., 2011, DOI: 10.1039/c1ja10041f) presented a combination of traditional PLS method and traditional univariate model that should improve the quality of quantitative elemental analysis in LIBS experiments. In this comment, we demonstrate that the proposed method is, in fact, basically flawed and its predictions are worse than the ones obtained using a standard univariate approach based on a calibration curve.

Abstract
In a recent paper, Wang et al. (J. Anal. At. Spectrom., 2011, DOI: 10.1039/c1ja10041f) presented a combination of traditional PLS method and traditional univariate model that should improve the quality of quantitative elemental analysis in LIBS experiments. In this comment, we demonstrate that the proposed method is, in fact, basically flawed and its predictions are worse than the ones obtained using a standard univariate approach based on a calibration curve.File in questo prodotto:
